Toxicity of Bacillus thuringiensis israelensis on the Nontarget Organisms Triops cancriformis, Branchipus schaefferi, Leptestheria dahalacensis (Crustacea: Branchiopoda: Notostraca, Anostraca, Spinicaudata)
In a blind and randomised study, early postlarval stages of the tadpole shrimp Triops cancriformis, the fairy shrimp Branchipus schaefferi, and the clam shrimp Leptestheria dahalacensis were exposed to different concentrations of a commonly available Bti suspension, equivalent to 0, 4.5 (recommended treatment concentration), 45, 450, and 4500 AA/l. No statistically significant correlations were...
متن کاملEffect of salinity stress on the life history variables of Branchipus schaefferi Fisher, 1834 (Crustacea: Anostraca)
BACKGROUND Freshwater anostracans inhabit ephemeral water bodies in which as the water level decreases due to evaporation the salt concentration increases. Thus, for most anostracans salinity becomes the major stress factor. RESULTS We tested five concentrations of NaCl (0 to 8 g/l) on the life table demography of Branchipus schaefferi fed Chlorella (alga). Age-specific survivorship curves of...
متن کاملEffect of tadpole shrimp, Triops longicaudatus, (Notostraca: Triopsidae), on the efficacy of the microbial control agent Bacillus thuringiensis var. israelensis in experimental microcosms.
Laboratory bioassays using Culex quinquefasciatus larvae evaluated the effect of tadpole shrimp on the persistence of Bacillus thuringiensis var. israelensis (B.t.i.) in water collected from the surface of field microcosms. Time elapsed since B.t.i. treatment, as well as presence or absence of soil and tadpole shrimp, affected B.t.i. persistence at the water surface in 15- and 30-cm total depth...
متن کاملEcology and distribution of large branchiopods (Crustacea, Branchiopoda, Anostraca, Notostraca, Laevicaudata, Spinicaudata) of the Eastern Cape Karoo, South Africa
A survey of the large branchiopod fauna of the Eastern Cape Karoo region of South Africa was undertaken to provide baseline biodiversity information in light of impending shale gas development activities in the region. Twenty-two waterbodies, including nine dams and thirteen natural depression wetlands, were sampled during November 2014 and April 2015. A total of 13 species belonging to four or...
متن کاملOral toxicity of Bacillus thuringiensis subsp. israelensis to adult mosquitoes.
The solubilized entomotoxin of Bacillus thuringiensis subsp. israelensis killed adult male and female mosquitoes of several genera and of various physiological states when it was administered orally. Adult mosquito mortality was further influenced when the preparation was contained in sucrose solution. The potential implication for the control of adult mosquitoes is discussed.
